また、6-[3-(3-t-ブチル-4-ヒドロキシ-5-メチルフェニル)プロポキシ]-2,4,8,10-テトラ-t-ブチルジベンゾ[d,f][1,3,2]ジオキサホスフェピンのみを比較例として安定剤kとした。
さらに、947gの6-[3-(3-t-ブチル-4-ヒドロキシ-5-メチルフェニル)プロポキシ]-2,4,8,10-テトラ-t-ブチルジベンゾ[d,f][1,3,2]ジオキサホスフェピンおよび53gのハイドロタルサイトをドライブレンドしたものを比較例として安定剤lとした。
安定剤をそれぞれ、温度50℃、湿度80%RHの恒温恒湿槽に4週間保管した後、JIS 0070 1992(フェノールフタレイン変色によるKOH滴定法)に従って酸価を計算した。酸価が低い程、耐加水分解性が高いことを意味する。この結果を表1に示す。
安定剤a~lを、温度50℃、湿度80%RHの恒温恒湿槽に4週間保管した後、口径100mm、足外径25mmの漏斗(止栓付)に安定剤をそれぞれ100g投入した。止栓を引き抜いてから安定剤が全て落下するまでの時間を計測した。落下時間が短い程、流下性が高いことを意味する。この結果を表1に示す。
